摘要
从雷达截面积(RCS)基本概念、傅立叶变换着手,论述基于快速傅立叶变换(FFT)技术的RCS测试原理。分析时域测试的优点及傅立叶变换在RCS时域测试中的应用前景。结果表明傅立叶变换技术对提高RCS测试精度具有显著效果。
Based on basal principle of RCS and Fourier transform ,the paper introduces time domain RCS measurements of ship using fast fourier transform, and analyses the advantage of time domain measurements and the application of FFT in time domain measurements. As a result, using the technique of fourier transform in time domain RCS measurements of the target can greatly improve measurements precision .
